Description

Hafnium diboride is a kind of gray crystal and has metallic luster, with high electric conductivity and stable chemical property. Besides, it is hardly reacted with all chemical reagents (except for Hf) in indoor temperature. It, a kind of new-type ceramic material with high-temperature comprehensive performance such as high melting-point, high thermal conductivity, inoxidizability, etc., is mainly applied in fields such as super high-temperature ceramics, high-speed aircraft nose cone and aerospace, etc. The hafnium diboride compound by our company based on new techniques is featured with high purity, even size distribution, large specific area, high surface activity and low apparent density, etc., based on which, powder materials of coarse-grain hafnium diboride and 60-nanometer hafnium diboride are core products.
